Sprayed this on my duckweed that had just about covered my 1/4 pond. Did about 1/3 of it this first day and about 4 hours later the section I sprayed had started to turn brown and die. 2 days and a big rain storm later and the duckweed is just about all gone. I will definitely keep a supply of this around to treat outbreaks as they occur.

We received the product yesterday with the boat applicator. We had to charge the battery even though it said it would come fully charged. After 9 minutes on a full charge the battery died and now the boat is stuck in the middle of the pond. Battery was supposed to last 20 minutes. Now I'm wondering if it will even work on the duckweed. Disappointed!

I had duckweed all over my pond that it looked like you could walk on it. I purchased just a quart to see if it would work. I sprayed the 32 oz. to 2 gallons of water in a back pack sprayer on a Thursday evening around 4:30pm and my wife sent me a picture on Friday at 2:00pm and at least 15 feet all around the edges were turning brown. By Sunday the pond started to clear up but after a week the duckweed was back but very thin so I purchased another half gallon.

I treated a 1/8 to 1/4 acre pond covered thick with Duckweed. I applied Dibrox two days ago, mix; 18 to 20 Oz to 1-1/2 gallons of water in a garden sprayer with the nozzle adjusted so it dispensed rain drop size droplets. In two days Duckweed is almost all TERMINATED. Only dead brownish duckweed remains after two days, even the middle area where my sprayer won't reach is dead. In a couple more days it will be totally gone!!!!! Easy...….

My pond is 100'x150' and was completely covered with duckweed. It is full of fish, frogs, turtles and we have a swan, 2 geese and 6 ducks. I was afraid to treat it with ANY chemicals but I took a chance on this product based on other's comments. It worked like magic - took about 8 days to totally clear the pond. I mixed 18oz with one gallon of water and simply sprayed the outside perimeter - a second treatment is not going to be necessary. I did not have one dead fish, frog, turtle, swan, goose or duck! I love this product and urge anyone with duckweed to use it with confidence.
